This invention relates to means for hanging sliding window sash and likeslidingly mounted members, whereby the sash may be opened and closed inthe ordinary manner,

0r swung laterally for the purpose of conveniently Washing the windowpanes or for other purposes.

Another object of the invention is the provision of a weight balancedsash having novel means for attaching the sash cord or chain thereto sothat the cord may be detached to release the sash, together with meansfor holding the cord against movement with respect to the window frame,whereby the cord will be retained in position to be again convenientlyattached to the sash.

With the above and other objects in view, the invention further includesthe following novel features and details of construction tobehereinafter more fully described, illustrated in the accompanyingdrawings and pointed out in the appended claims.

- In the drawings s Figure 1 is an elevation showing a portion of awindow with the invention applied.

Figure 2 is an enlarged fragmentary vertical section illustrating themeans of attaching the sash cord to the sash with the parts in lockedposition. Figure 3 is a view similar to Figure 2 showing the parts inreleased position.

Figure 4 is an enlarged fragmentary sectional view taken on the line 44of Figure 1.

Figure 5 is a similar view showing the sash hingedly supported and swungto an open position.

Figure 6 is a face View of a portion of a window frame showing the cordcarried section of the attaching member.

Referring to the drawings in detail wherein like characters of referencedenote corresponding parts, the reference character 10 indicates awindow sash which is slidingly mounted in a frame 11. One side of thisframe is provided with'a longitudinally extending groove 12 but theadjacent edge of the sash 10 does not enter this groove and the usualretaining and guide strips at this side of the frame may or may not bedispensed with. The sash however is of the slidingly mounted weightbalanced type and for this purpose has attached. thereto one end of acord or chain 13, the attaching means which forms a part of the presentinvention being of a character to permit of the cord 5 being readilyattached to or detached from i the sash. For this purpose there isprovided a sectional cord attaching member which comprises a section14and asection 15'. The section 14 isslidable in the groove 12 of thewindow frame, while the sectionv 15 is positioned within a groove 16provided in the adjacent stile of the sash 10.' The groove 16 may or maynot be, but preferably is provided with a metal lining 17 within'whichthe section 15 has a sliding fit. A small section of thelsash is left inthe groove 12 to provide a sea I I The section 15 is provided withspaced parallel inclined slots 18 which receive pins 0 19 extendingtransverselyof the groove 16, so that the section 15 may have a lateralsliding movement within the groove 16 and will be moved verticallyduring such sliding movement. Guide pins 20 have their inner endssecured to the sash 10 and are received within parallel inclinedopenings 21 provided in the section 15. The section 15 further includesa transversely U-shaped metallic member 22 within which is secured ablock 23. This block is shaped asshown in Figures 2 and 3 of thedrawings so that the side wallsof the member 22 extend beyond the outerlongitudinal edge of the block for the major portion of their length, asindis5 cated at 24. When the sect-ions14 and 15 are connected in amanner to be explained, these extended portions 24 of the side wallswill enter the groove 12 upon opposite sides of the section 14. i j soThe section 14 comprises a hollow transversely rectangular casing whichis provided with an opening 25. Extending across this opening is a pin26 which is adapted to be engaged by a tongue 27 which extends from ,95the adjacent face of the section 15. By reference to. Figure 3 ofthedrawings it will be seen that when the section 15 is moved outwardlyand'downwardly, the tongue 27 will occupy a position above the pin 26.When the sash is raised, the weight (not shown) upon the Opposite end ofthe sash cord 13, will move the section 14 upwardly in accordance withthe movement of the sash 10 so as to balance the sash. WVhen the. sash10 is moved downward, engagement of the tongue 27 with the pin 26 willbring the section 14 and the adjacent portion of the sash cord 13downward, as will be readily understood.

The purpose of the invention is to release the sash from the cord sothatthe sash may be swung inward, and in order to permit of this inwardswingingmovement, the'opposite edge of the sash 10 may be hingedly or.otherwise mounted. Various means may be devised for this purpose, but itis preferred to employ the means shown and described in mycopendingapplication. This means consists of a hinge which embodies astationary hinge plate 27. This plate is preferably mortised within thewindow frame within a groove defined by strips 28 and 29. The strip 29is cut away to receive spaced lugs 30 which are carried by the plate 27and this plate is provided with an opening 31. The opening 31accommodates a plate 32 which is hingedly secured to the plate 27 meansof a link 33 whose opposite ends receive pins 34 which extend throughthe lugs 30 of the plate27, and through lugs 35 which extend from theplate 32. The lugs 34 are also received within the cut-away portion ofthe strip 29.

The outer end of the plate 32 is provided with a flange 36 within which'is provided a groove 37 and this groove "slidingly receives one edge ofa plate 38 which is securedto the adjacent face'of the sash 10. Theopposite edge of this plate engages within grooves 39 provided in thelugs 35, so that the'plate 38 is slidingly mounted with respect to thehinge plate 32. When the parts are in the position shown in Figure 4 ofthe drawings, the sash may be raised and lowered inthe ordinary manner.V

,The plate 38 carries a sleeve 40 which may or may not be. integral withthe plate and which accommodates a locking bolt 41 and this bolt isprovided with a finger piece 42 which extends through a slot 43 providedin the sash. The bolt -41 is adapted to enter an opening 44 provided inthe plate 32, and when the bolt is engaged within this opening, the sash10 will belocked to the hinge plate 32.

Normally, the parts are arranged as shown in Figure 4 of the drawingswith the bolt 41 disengaged from the plate 32, so that the sash 10 maybe raised or lowered. WVhen itis desired to swing the sash laterallyupon the hinges, the finger pieces 42 of each hinge are slid inward ortoward the adjacent ortion of the window frame, so that the bolt 41 willenter the opening'44. The sash cord attaching member is then operated tomove the section 15 from the positionshown in Figure 2 to the positionshown in Figure 3, so that this edge of the sash will be released andthe sash may be swung to the position shown in Figure 5.

In order to manipulate the section 15 of the cord attaching member, thelining 17 of the groove 16 has extending therefromspaced aperturedcars45. Pivotally mounted between .these cars upon a pivot pin 46 is a lever47 This lever includes a finger piece and arm 48 which engages betweenspaced projections 49 provided in the upper end of the section 15. Byswinging the finger piece 47 upward to the position shown in Figure 3 ofthe drawings, the section 15 will be moved inward and upward so as todisengage the tongue 27 from the pin 26. The section 15 is then freefrom the section 14 so that these sections may be moved independently ofone another. v r

. In order to prevent the weight from drawing the sash cord 13 upward,the section 14 has pivotally mounted therein a dog 50.-

This dog has one of its-ends forced through an opening 51 provided inthe casing of the section 14 so that it may enter. an opening 52provided in a plate 53 which is secured within the bottom of the slot 12of, the window frame. A spring 54 is utilized for forcing the dogthrough these openings, this spring engaging the lower end of the dog sothat as soon as the opening 51 registers with the opening 52, the dogwill'be forced inward. The opposite end of the dog however is arrangedin the path of the tongue 27, so that when the parts are in the lockedposition shown in Figure 2, the d0g'50 will-be pre vented from enteringthe opening 52 and the section 14 which is attached to the cord may havefree sliding movement within the slot 12. Before manipulating the fingerpiece 47 to release the cord, the sash is moved into position so as topermit the dog to enter the opening 52, so that when the sections arereleased, the spring 54 will force the dog into' the opening 52 andpreventthe' sash cord from moving upward'under the influence of the sashweight; When the parts are in proper position to lock the sash to thehinges, the dog will be in proper position to enter the opening 52. i s

The lever 47 carries laterally spacedextensions 55 of a length to engagethe frame 11 upon opposite sides of the slot 12, and this frame 11 isrecessed upon each side of the slot as shown at 56. Therecesses 56 areso located as to permit the lever 47 to be operated to move the section15 only when the section 14 is in proper position to be locked to theframe 11.
